[U-Boot] [PATCH v5 1/3] ARM: Tegra: FDT: Add USB EHCI function for T30/T114

[Jim Lin]

Add DT node for USB EHCI function.
Add support for T30-Cardhu, T30-Beaver, T114-Dalmore boards.

Signed-off-by: Jim Lin <jilin at nvidia.com>

Changes in v2:
 - Remove PLL parameters from dt file
Changes in v3:
 - Change VBus GPIO from H.05 to DD.04 for Beaver board.
Changes in v4:
 - Change Beaver VBus GPIO to H.05 and value to 0 for polarity to be High.
   I don't have Beaver board. So this needs somebody to help test.
   Thanks.
 - Change Cardhu VBus GPIO value from 3 to 1 because only bit 0 is meaningful.
Changes in v5:
 - Move changes on fdtdec.h and fdtdec.c to patch 2/3
 - Modify PHY type to hsic for USB2 port
